A much more aggressive British mutation extends to the Czech Republic, but it is no more dangerous than the original. What about the South African type of coronavirus?
The British mutation spreads much faster, but according to some doctors, it is also more dangerous. For the new type of coronavirus, I would talk about variants in which there are more mutations. These are the South African and Brazilian variants, which seem really threatening. To date, epidemiological data do not support this, but it appears that they could be resistant to antibodies caused by vaccination or disease. This would mean that even these people could become infected again.
